What passes for journalism these days
I found this article on the front page of the online edition od the Deseret News. I'll sum it up for you:
Experts disagree about whether or not the snowpack amounts in the Rocky Mountains are decreasing. Somewhat unsurprisingly, the Sierra Club says they are decreasing, and blames global warming. The mayor of Salt Lake City agrees with them. No details are given to show the validity of either claim.
Props to the reporter for at least looking for someone to disagree with the mighty Sierra Club, which is something most reporters will not do. After all, the Sierra Club speaks Truth to Power, which we all know is something that journalists aspire to do in their finest moments.
But in essence, the facts left out speak more then the facts put in. Which expert is more credible? Was either claim peer reviewed for proper scientific and statistical analysis? What are the actual numbers involved?
Here's what we get from the article:
Does it seem obvious to ask how much lower than average those 11 years were? And if the other five years were significantly above average? Is it too hard to provide a statiscal analysis to determine a trend for 16 years, and is that even really enough? The opposing expert has 30 years of data. Isn't that a better sample size?
The article also says that this decline threatens the ski industry. So exactly how much less snow is too little to ski on?
I'm not a meteorologist, but I do know a few things: warmer weather means more moisture in the air (due to evaporation and the fact that air holds more moisture the warmer it gets), so how does this translate into drought? And if the winters are, say 5 degrees warmer than normal (and this is being rather generous, I think), then how many less days of potential snowfall are there, really?
The article is balanced in its ignorance, managing to give both sides of the argument without clarifying either.

Here's what we get from the article:
The Sierra Club's press release announcing the news conference says, "Utah's water supply is currently being threatened by warmer winters caused by global warming."
The study says that in the upper basins of four rivers studied — the Columbia, Missouri, Colorado and Rio Grande — human-caused climate change increased temperatures, caused more warming in the winter and spring and reducing the snowmelt.
Snowpack levels were below average in the Colorado River Basin for 11 of the past 16 years, it adds.
